> yet I assume you can distinguish good development practices from bad

Uh. We're not talking about knowing what good is, which is completely irrelevant to anything in this thread. You made a claim without qualification about what it is more likely for PMs to do. I can't tell if you've lost the chain or are engaging in some kind of motte and bailey fallacy. Either way it's a bad sign for this conversation.

I'm going to summarize the threads so far. I hope it highlights why what you've said sounds so silly:

Someone: "I see X failing to do Y."

You: "X definitely do Y. Why would you think that X aren't doing Y? Doing Y is the obvious thing for X to do."

Someone: "I literally am seeing it happen right now."

You: "Well then those X are bad."

Someone: "Yeah, no shit. They just said as much."

You: "But most X would do Y."

Someone: "In my experience that is false."

Someone else: "Mine too."

Someone else: "Mine as well."

Someone else: "Same."

You: "The bad ones shouldn't have their jobs."

Someone: "They do though."

You: "But we can tell which ones are the bad ones."

Someone: "Bartender, another drink please."
